APPARATUS FOR BORING AND DISINTEGRATING EARTHY MATTER.

SPECIFICATION forming part of Letters Patent No. 639,836, dated December26, 1899.

Application filed January 3, 1898.

To all whom it may concern:

Be it known that I, GEORGE WETHERBY, a citizen of the United States,residing in the city of Duluth, in the county of St. Louis and State ofMinnesota, have invented new and useful Improvements in Apparatus forBoring and Disintegrating Earthy Matter, of which the following is aspecification.

This invention relates to improvements in mechanism in devices for usein boring into the earth,frozen eartlnor rock, and is designed for usein placer-mining where the dirt is too hard or too much frozen to dig toadvantage with the usual outfit of the placer-miner.

Theinvention consists, essentially, of a boring-tool and a frame uponwhich said boringtool is mounted.

The invention further consists in the novel construction and arrangementof the several parts of the device,hereinafter described,illustrated inthe drawings, and more particularly pointed out in the claims hereuntoappended.

In the drawings, Figure 1 is a side elevation of a portion of myboring-machine, showing the rotating and reciprocating mechanism foroperating said boring-tool. Fig. 2 is a top plan view thereof. Fig. 3 isan end view of the device, showing the reciprocating mechanism. Fig. atis a detail.

Similar letters of reference indicate corresponding parts in all thefigures.

Referring to the drawings by letters, A represents the boring-tool-operatin g frame,which is provided near one end thereof with atransverse shaft f, journaled in side beams a a of the frame A. On oneend of said shaft, to the inside of the frame,is mounted an eccentric k.Near the opposite end of this shaft, mounted thereon, in the inside ofsaid frame is a gearwheel 70', which meshes with the pinion d, mountedupon a shaft E, also journaled in the frame A, having one end thereofprojecting beyond the frame and provided with a The end of the shaft fon one side of the frame projects slightly to the outside and hasmounted thereon a large fiywheel b. In the outer face of this fiy-Wheelb,extending across the face thereof, is a groove or slot 11, into whichis set and moves to and fro a traveler 5 Upon this frame A is securelymounted a bracket S, having its upper ends or legs 8' Serial No.665,591. (No model.)

8 set at right angles and provided with asuitable bearing, into andthrough which extends the upper end of a suitable boring-tool holder D,which is provided with a longitudinal groove (1 near the upper endthereof and extends downward for about one-half of the length of saidholder. Upon said holder D, between the brackets ss,is mountedaratchetwheel 72., provided with a lug (not shown) adapted to fit intothe groove a in the holder D for the purpose of rotating said holder andat the same time permitting a vertical reciprocation thereof, as isapparent.

U1 is an operating-lever swiveled at n upon the bracket S, having oneend thereof resting upon the surface of the eccentric la and theopposite end thereof turned at right angles and engaging theratchet-wheel h.

u, is a suitable spring secured to the bracket S and bearing against thelever 10 for the pur pose of holding the lower end of said lever inconstant contact with the periphery of the eccentric k. I

d2 is a suitable connection, consisting of a collar and binding-screw,for securing the boring-tool to the holder D.

d is a suitable collar or link upon the boring-tool or drill and isprovided with means for engaginga hook j on the traveler b ,Whereby,through the fly-wheel b, the said boringtool is caused to reciprocate.

This device is used chiefly forboring through frozen earth and suchother deposits as afiord great resistance. When the ground to be workedin can be bored by the use of an earthauger, I prefer to remove therotating and reciprocating boring-tool and replace it by arotatingboring-tool or earth-auger. This auger has at its boring endthree points arranged to properly cut and loosen up the earth.

This boring-tool-manipulating device may be operated either by hand orsteam power, depending very much upon the character of ground in whichWork is being done.

When the boring-tool has been placed in position for boring, power isapplied to the crank g by either hand or any other desired means. Whenthe crank g is turned, the shaft E, connected thereto,will revolve,causing the pinion d,mounted thereon,to revolve the gearwheel is,meshing therewith, which revolves the shaft f and also the eccentric is,mounted D and tool connected therewith. At the same time with thisvertical reciprocation of the tool the eccentric 7c, keyed upon theshaft f, will oscillate the lever it, which engages the ratchet-Wheel h,mounted upon the holder D, turns said ratchet-wheel and the holder D, towhich it is secured, one notch at each revolution, and consequently ateach reoiprocation of the drill.

When the character of the material operated upon warrants, thereciprocating and rotating tool is removed, and in place thereof issubstituted a rotating tool. The operation of the anger is the same asthat of the drill with the exception that it is not reciprocated. Bymeans of a suitable derrick or other means the dirt is conveyed from theboring-point to a reducing-tank and there subjected to the action ofsteam for the purpose of more thoroughly disintegrating it.

Having thus described my invention, what I desire to secure by LettersPatent is 1. In a machine of the character described, the combination ofthe main frame, the toolholding supporting-bracket having legs 8, s,mounted thereon, a shaft suitably mounted in said frame and carrying aneccentric 7t, and a fly-wheel I) provided with a channel or guide acrossits outer face, a hook-carrying traveler adapted to slide back and forthin said guide or channel, and a lever having one end thereof engagingwith the eccentric on said shaft, and the opposite end adapted to engagea suitable pinion; with a boring-tool holder mounted in the tool-holding bracket S, a ratchet-wheel h secured on said tool-holder, between thelegs 8, s of the bracket, in such manner as to permit a longitudinalreciprocation thereof, and a tool secured in the lower end of saidholder and looselyconnected to the sliding traveler on the fly-wheel,bymeans of a hook,means for operating said mechanism to simultaneouslyreciprocate and rotate the said tool, as set forth.

2. In a machine of the character described the combination of the mainframe, the boring-tool-supportiug bracket having legs 3, s mountedthereon, a shaft suitably mounted in said frame and carrying aneccentric 7c, and a fly-wheel 1) provided with a channel or guide acrossits outer face, a hook-carrying traveler adapted to slide back and forthin said guide or channel, and a lever pivoted on said frame and havingone end thereof engaging with the eccentric and the opposite end adaptedto engage a suitable ratchet-wheel on the toolholder; with a holdermounted in said toolholding bracket, a suitable tool mounted in saidholder and means substantially as described whereby the said traveler bmay be connected to or disconnected from the toolholder to give either asimultaneously rotating and reciprocating motion to said drill, ormerely a rotating motion, all constructed and arranged substantially inthe manner and for the purpose specified.

GEORGE WETIIERBY.
